811.0 cg = 811.0/100 g = 8.110/1000 kg
=0.008110 kg
Then use formula to calculate concentration in ppm.
Keep the answer to 4 significant figures.
6. The solubility of salt 'A' in water at 60°C is 27.5 g. Find out how much of the same salt will dissolve in 75.5 g of water at 60°C (2 Marks)
The mass in the equation for calculating parts per million (ppm) can be in either grams (g) or kilograms (kg). However, it is important to ensure that the mass units are consistently either in grams or kilograms throughout the equation to avoid any unit conversion errors. In the given question, you have the mass of water given in kilograms (kg), so it would be more convenient to use kilograms for the mass of solution.
